CROSS REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application 61/475,621, filed Apr. 14, 2011.

BACKGROUND

Vaginal dryness is a common concern for which remedies are known, including vaginal lubricants. Dryness is a common following menopause in women and also after childbirth and may result from diseases and/or treatments thereof. Vaginal dryness can negatively impact the psychological and physical health of women.

In recent years, consumers have become increasingly concerned about the safety of synthetic materials that are consumed or used on the body. There is a growing movement toward organic materials in products such as shampoo. At present, there is a need for organic vaginal lubricants and particularly lubricants with high performance.

SUMMARY

A vaginal lubricant of primarily organic materials has excellent properties for relieving vaginal dryness.

FIG. 1 shows viscosity versus shear rate of a sample of the composition defined in FIG. 3 at 21 C, where the speed of the viscosimeter was first reduced and then increased so that the viscosity is shown to change after being sheared.

FIG. 1 shows viscosity versus shear rate of a sample of the composition defined in FIG. 3 at 37 C, where the speed of the viscosimeter was first reduced and then increased so that the viscosity is shown to change after being sheared.

FIG. 3 defines the composition tested.

DETAILED DESCRIPTION OF THE EMBODIMENTS

A vaginal lubricant compound includes Shea Butter, Sun Flower Oil, Cocoa seed extract, Evening Primrose, Cera Alba, Borago seed oil, Lavender Flower extract, and Aloe Vera in such combination as to provide a shear thinning effect.

Various strain forces were applied to the above compound to determine its properties. A change was appreciated in texture from a solid to a liquid with applied shear forces with and without changes in temperature as well. The compound, consequently, with the applied ratios as seen in the following provides the property changes described.

As shear rate increases 1/sec at body temperature of 37 degrees Celcius, viscosity measured in cP decreased from approximately 700 cP to 350 cP (see graft). At room temperature (21.1 degrees Celcius), viscosity changed from 2500 to 500 cP with speed rate forces in RPM and shear rate as well. Change in viscosity was appreciated with change in temperature, change in shear stress and shear rate unlike other vaginal moisturizers on the market.

Attached graphs and data listings show the results of testing. Conditions were selected so that all measurements were between 10 and 100% of full scale range. A Brookfield RVDV-III Ultra CP Rheometer was used; a CPE-52 cone spindle was used for tests at 21° C., and a CPE-41 cone spindle was used for the test at 37° C. Sample temperatures were maintained by using a Brookfield TC-502 P Programmable Temperature Bath connected to the sample cup. The compound was thixotropic and the viscosities measured at various shear rates were lower at the higher temperature. The larger CPE-41 cone spindle was used at 37° C., to ensure sufficient sensitivity when measuring the lower viscosities.

In addition, the present compound, no bacterial changes were appreciated in microbiologic testing by Micro Quality Labs, Inc. at 1 month of testing with a challenge test and at 1.5 years later as well. Certificate of Analysis was received indicating no growth with Enrichment testing, <10cfu/gm for TPC and <10cfu/gm for yeast and mold.

The compound is expected to improve vaginal tissue quality and decrease the incidence of dyspareunia without the concerns and contraindications of hormones. The ingredient composition along with the viscosity findings are unique to the product in this category of vaginal lubricants and moisturizers.

The foregoing descriptions apply, in some cases, to examples generated in a laboratory, but these examples can be extended to production techniques. For example, where quantities and techniques apply to the laboratory examples, they should not be understood as limiting.
